Fold the sensor

Dynamic characteristics, refers to the sensors in the input changes, the characteristics of its output. In practice, a dynamic characteristic of the sensor used to use it for some standard input signal response to said. This is because the sensor response to standard input signal is easily obtained by the experimental methods, and its response to standard input signal and its response to any input signal between certain relations, often know the former can presumption of the latter. The most commonly used standard input signal has two step signal and sine signal, so the sensor's dynamic characteristic is also often said by step response and frequency response.

Fold sensor resolution

Resolution refers to the sensor can be felt by measuring of the capability of the smallest change. That is to say, if the input amount from a non-zero value change slowly. When the input changes value does not exceed a certain value, the output of the sensor will not change, i.e., the change of sensor input to this resolution not to come out. Only when more than the quantity of input resolution, the output will change.

Fold sensor sensitivity

Sensitivity refers to the sensor under the steady working condition sensor output delta y to input changes the ratio of delta x.

It is a input output characteristic curve of the slope. If the sensor show linear relationship between output and input, the sensitivity of S is a constant. Otherwise, it will change along with the change of input.

When the output of the sensor, input amount of dimensional phase at the same time, the sensitivity can be understood as magnification.

To improve sensitivity, can get high accuracy of measurement. But the higher the sensitivity, the measuring range narrow, stability tend to worse.
